COP28: Green Hydrogen Is Most Water-Efficient Form Of Clean Hydrogen, Uses One-Third Less Water Than Blue Hydrogen

Green hydrogen consumes less water than other types of hydrogen which aim to reduce greenhouse gas emissions. This makes green hydrogen the best option for water security.

Green hydrogen, which is hydrogen produced by splitting water into hydrogen and oxygen using renewable electricity, is the most water-efficient form of clean hydrogen, and uses about one-third less water per kilogram of hydrogen produced than blue hydrogen. Therefore, it is important to prioritise green hydrogen to minimise water security threats, a report published by the International Renewable Energy Agency (IRENA) on December 10, 2023, during COP28, said.
